Abstract: 6147. Riecken, H. March 12. Amalgams, obtaining.-Relates to the electrolytical treatment of ores and slimes for the recovery of precious metals, such as of gold, therefrom, the essential feature being that a stream of mercury is caused to flow continuously down a vertical or inclined metallic cathode. In the open vat A shown, there are inclined copper sides B down which mercury flows in thin streams from a trough C through slits c therein, the mercury being either continuously or intermittently removed from the gutter b at the bottom of the tank through a tap D into a tank E from which it can be again raised, as by the pump F, to the trough. The anode is formed of rods G of carbon or other suitable material, projecting radially from a shaft H, which turns in bearings h, h, and is rotated by a driving-pulley S. The electrolyte consists of the slimes &c., and potassium-cyanide solution, to which may be added an oxidizing-agent. The tank may be made shallower than here shown, and the electrolyte may be agitated by oscillating, as opposed to rotating, arms. A hard adherent amalgam collects on the copper sides, and ordinary amalgam may be also found mixed with the mercury. The precious metal is recovered from these amalgams by known methods.

Granted: 1898-09-10
Abstract: 13,816. Parsons, J. H. June 21. Annular-chamber type.-The piston 14 is formed with the sleeves 12, 13, loose on the lengths 8, 10 of the shaft, and a second piston, not shown, but similar to 14, is cast with the sleeve 16 fast on the length 9. The shaft 30 carries a disc 31 having diametrically - opposite pins 32 carrying pivoted links 71, 72, the opposite ends of which are secured to the crank arms 33, 34, attached respectively to the sleeve 12 and shaft 8. The steam chamber 27 communicates through ports 28 with the chamber 73, which communicates with the cylinder by means of an elongated arcshaped opening, controlled by the sliding plate 36, Fig. 3, which is actuated by the rack-and-pinion gear shown. The exhaust fluid escapes through the ports 25 to the chamber 24 and pipe 26. In action, one piston acts as an abutment for the other. Figs. 8 and 9 show valve gear for reversing the engine. The lever 43 is connected by the arm 44 to the valve 42, which has ports 46 and a lateral recess 47. The cylinder cover has ports 48, and alongside the steam chamber 40 are exhaust passages 49. When the valve is in the position shown in Fig. 8, steam &c. passes through the port 45, recess 47, and one of the ports 48 to the cylinder, while the exhaust takes place through the other port 48, one of the ports 46, and an exhaust passage 49. By shifting the valve 42, the inlet port becomes the outlet, and vice versÔ. Figs. 12, 13, and 15 show a modified form of reversing-mechanism. The steam port 77 is controlled by plates 78, 79 having respectively racks 80, 81 with which the pinions 65, 64 gear. These pinions are carried upon the shaft 54 and a sleeve respectively. In Fig. 12, the lever 56 is shown in mid position ; when it is moved towards the right, the lever 59 oscillates and rotates the pinion 65, thus moving the plate 78 relatively to the steam port ; at the same time the cam lever 53 is turned on its pivot 60, and by means of the rod 62 and curved plate 89 the plates 91 are moved laterally so as to control the exhaust ports 92. On turning the lever 56 to the left of the mid position, the lever 58 is actuated, the pinion 64 rotated, and the plate 79 uncovers the port 77 at another port, while by the means described the exhaust ports on one side of the cylinder will be closed, and those on the other side opened. Other slight modifications, connected chiefly with the reversing-gear, are described. The pistons have end recesses, and holes may be bored through the solid portions, so as to equalize the pressures on each end.
